Patented Mar. 13, 1945 UNITEDV STATE o UsnIoN i Arthur Adams, Iios S.Karpen & Bros., Chicago, lll., a corporation h of Iliinois i Angeles,Calif., assignor to Application June 24, 1942, serialize. 448,205 p i l6 claims.. (or 5-J-251) This invention relates to a. cushion, and moreparticularly to a soft -highly-resilient cushion structure having aplu'ralityof layers of resilient material therein. v

An object of the invention is to provide a cush- `ion of extremesoftness while at the same time maintaining a relatively high degree ofresiliencyI in the cushion. I Another object is to provide inl a cushionhating aspring unit as a core, a plurality of layers of material ofdifferent resiliencies and -tangular, with substantially yflat upper,lower an side surfaces.

'Y About the spring unit II is a. pair of pads I6 and Il, which arepreferably formed of a resilient and only slightly-compressiblematerial, such, for

. example, as tightly curled hair. The pads I6 and `l'lextend across thetop and bottom surfaces of the spring unit IIr and cover the same.Preferably, the pad t6 is provided withdepending pordifferent degrees ofcompressibility. A further i object is to provide in a cushion having aspring unit as a. core, a layer of resilient material which is onlyslightly compressible and a second and outer layer of resilient materialwhich is highly compressible. Y I

Another object of the invention is to provide a cushion having aplurality of `layers of curled hair, the outer layer beingu formed ofloosely curled hair of high compressibility and the inner layer beingformed of tightly curled hair'which is only slightly compressible. Yetanother object is to provide in acushion, a spring unit and a resilientApad extending about the same, the assembly being disposedwithin acasing which contions I8 and I9 which cover two of the sides of thespring,v unit. Similarly, the pad I'I may be 'provided with`upwardly-extending portions 2l) tains compartments `of a soft andhighly-compressible material. I

Other features andadvantages of the inven-r tion will appear from thefollowing specification and drawings, in ,which- Fig. l is a transversesectional viewof a1 cushion i embodying the invention, the spring unitin the central portion of the cushionbeing shown inelevation andhavingits casing partly broken away to show the spring therein; Fig.- 2is a rdetail fragmentary longitudinal sectional view of the cushion;Fig;` 3 is a perspective view of the resilient pads used in the cushion;and Fig. 4 is a perspective view of the casing for the cushion showing ahighly-compressible materialv disposed within the compartments inthecasing.

In the embodiment of the inventionl described herein, the cushion I0includes a spring unit II which forms the core of the cushion. Thespring unit Il may includea plurality. of helical springs I2 disposed inside-by-siderelation, with vthe up.- per and lower ends of the helicalsbeing in the same planes to` provideat upper and lower surfaces for theunit.` .Preferably,leach of the helical springs is enclosed'vvithin afabric casing I-3 of muslin or the like. The casings I3 maybe se; curedto each other at the'seams I4.` Preferably,

the casings and the helical springs-are'tied-'together by threads orstrings I5 to form-a unitary spring body. The spring unit is preferablyrecand 2I which cover the other two sides of the spring unit.

'As Aseen particularly in Fig. 3, the pads I6 `and I1 may be in the formof interlaced, stitched or garnetted pads in which a suitable resilientand slightly-compressible material is secured to a fabric backing 22 bymeans of stitches 23. The resilient and slightly-compressible materialmay f comprise tightly curled Vhorse or' cattle hair, or a mixture ofeither or both of these with hog hair, moss, cotton, sisal, tula ber,and may, in fact, consist of a rubberized pad. At any rate, the padshould possess substantial resiliency for the cushioningeiect and at thesame time should be only `slightlycompressible so that when pressure isexerted on the surface of the cushion, the spring core in :the cushionwill not be felt through the padding by the user of the cushion.

. vThelpads `Iii and I1 extending about the spring unit I I? may, inturn, be enclosed by a casing 24 (Fig. 4).- The casing 24 may includeside walls 25 and 2li, a top wall 2l, and a bottom wall 28. Endwalls offabric may, if desired, be provided and may extend between the sidewalls 25 and 26 and top and bottom walls 21 and 2B. The fabric may beof,v any suitable material, preferably of a light material;

A second casing 29 may extend across and overlie the top Wa-ll 2'I` ofthe casing 24, the casing 29 preferably being spaced above the top wall21 but being joined theretoat the edges 30 and 3|. Flexible fabricpartitions 32 and 33 may be arranged at. spaced intervals between thefabric sheets24 and 29,'the fabric partitions preferably extendingvertically between two sheets and longitudinallyithroughout the lengthof the cushion. A casingsheet 34, similar tothe casing sheet 29, may bedisposed below the bottom wall 28 of the 38,may\be disposed betweenthebottom wall and casing sheet134.

. The nexible fabric 'partitions a2 and as provide cushion. Atrthefsametime, the' matialshould be resilient. Preferably, the materialis looselycurled hair, such as horse or cattle hair, butA other similar materials,such as kapok, silk floss;

or milkweed oss, may be used.

'An outer cover or casing 4l) may extend yabout l and enclose-the entireassembly. 'The outer cover or casing 40 may include' atop walldl, sidewalls 42 and a bottom wall 43, the walls being joined by seams at thecorners. of ,the cushion.,

When the cushion is used and pressure is,

placed upon the upper surface, the material 3S provides e. softhishlyreempressible surface which gives the cushion the desiredsoftness. 'The same material 3g) also provides-a certain amountofresiliency in the cushion.4 The pads I6 and l'l are only slightlycompressible and are also resilient, while the spring corek l l ishighlyfresistant te Compression but possesses great resiliency. Thepressure on the surface of the cushion will notcause the helical springsof the spring unit Il tobe felt through the layers of resilient mate.-rial because the slightlyw-compressible padsfl 6 and Il are interposedbetween the soft outer layer and the spring unit.

Although the invention has been described. in connectionl with a specicembodiment, itwill be understood that changes and modifications may bereadily made without departing from thespirit and scope of theinvention.
